I dont see where did you heard mention of Dažbog? It is : "Daj Bože, daj sitnu rosu" "Give God give tiny drew".
Here is text from Trkulja's site.
Besides it, spot which you posted does not show Dodole at all.
Just to make clear, I do believe dodole is remanant of Pagan practices, I just pointed to wrong version of text and unedequate spot.
